Insertion of junction/Repair of pipeline using standard/large/extra wide couplings
| 1. Cut section from pipeline using pipe cutter or disc saw and remove. |  |
| 2. This should be about 20mm longer than the junction or new section of pipeline to be inserted. |  |
| 3. Cut section from pipeline using pipe cutter or disc saw and remove. |  |
| 4. OR Position new section into pipeline. |  |
| 5. Place pencil mark 1/2 a coupling width from each joint. |  |
| 6. Using these pencil marks, centre a coupling over one joint at a time. |  |
| 7. Tighten the worm drive units in sequence across the width of the coupling to torque recommended. (Alternatively tighten the central shear ring then the clamps). |  |
| 8. After assembly carefully tamp bedding under pipeline. |  |
Note: When jointing concrete pipes (particularly vertical cast) it is often necessary to apply a neat cement grout to the sealing area, providing a smooth surface and ensuring an airtight seal. On some pipes (concrete and iron) it may be necessary to smooth out the mould line in the area of the joint. With Standard Large Couplings this requirement may not be necessary.
